GREEN BAY - Police are investigating whether a Green Bay man recently arrested in Laos for a sexual assault may have had other victims.

Jimmy Choumemany, 28, was arrested Oct. 12 near the city of Vientiane, Laos on Nov. 1. He was returned this week to Brown County, where he was charged with first-degree sexual assault involving the use of a dangerous weapon.

Choumemany's arrest ended a nearly four-month search that extended overseas and involved numerous agencies, including the FBI, law enforcement in Laos and Interpol, the international police organization that helps track warrants overseas.

He is accused of sexually assaulting a woman July 22 in a downtown Green Bay alley. Authorities began searching for Choumemany after a member of his family identified him in surveillance images posted by detectives online.

During a news conference Wednesday, Green Bay Police Chief Andrew Smith said video of the Green Bay assault shows Choumemany was actively looking for a victim and "pounced" on the woman in the alley. She was able to fight him off.

"To me, that's the sign of a predator. That's the sign of someone who either has done this before, but will certainly do this again, and that's why it's good to have him off the streets," Smith said.

Family members told police that Choumemany had a history of improper interactions with women. They also described another incident in which, they said, he chased somebody down and assaulted them. Green Bay police told USA TODAY NETWORK-Wisconsin in August that they were unsure if that incident was ever reported to law enforcement.

"We're also looking at a couple of other incidents in the last six months to a year to see if there are any connections and checking similarities of unsolved cases. That's kind of an ongoing thing, and we have evidence to compare and statements to obtain," said Green Bay Police Lt. Rick Belanger.

Choumemany traveled between Thailand, Laos, Chicago and Green Bay over the last 10 years. Those movements also are being reviewed by authorities.

"There is a possibility that he would offend somewhere, run, offend there and run to another place. This was a guy we definitely wanted to get off the streets and be held accountable. Especially, if he is traveling, not just in our country or state, but if he is traveling the world and doing this to females he needs to be stopped," Belanger said.

Interpol checked with other agencies during the investigation to see if there were any other incidents reported in other parts of the world.

"I haven't heard anything from the federal government that they found other cases at this point," he said.

Choumemany is due in court Dec. 4 for an adjourned initial appearance.
